ABSTRACT

Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV. We improved the sensitivity to spectral lines at high energies using large-zenith-angle observations and a novel background modeling method within a maximum-likelihood analysis in the energy domain. No linelike spectral feature is found in our analysis. Therefore, we constrain the cross section for dark matter annihilation into two photons to ⟨σv⟩≲5×10^{-28} cm^{3} s^{-1} at 1 TeV and ⟨σv⟩≲1×10^{-25} cm^{3} s^{-1} at 100 TeV, achieving the best limits to date for a dark matter mass above 20 TeV and a cuspy dark matter profile at the Galactic Center. Finally, we use the derived limits for both cuspy and cored dark matter profiles to constrain supersymmetric wino models.

ABSTRACT

PURPOSE: The aim of this study is to develop a Spanish version of the Body Image Scale (Hopwood et al. Eur J Cancer 37(2):189-197, 2001) and to analyze its psychometric properties in a sample of women with breast or gynaecological cancer. METHODS: The Spanish version of the Body Image Scale was developed using a forward and backward translation technique. A total sample of 100 women who had undergone radical surgery for breast (n = 50) or gynaecological cancer (n = 50) completed the scale. RESULTS: Factor analysis resulted in a single-factor solution, both in the total sample and in the two subgroups, accounting for >76 % variance. Internal consistency (Cronbach's alpha) was 0.960. The Spanish version of the Body Image Scale correlated negatively with self-esteem (r = -0.733), quality of life (r = -0.632) and age (r = -0.643) and positively with depression (r = 0.832) and anxiety (r = 0.564); all p values < 0.01. CONCLUSIONS: To our knowledge, this is the first study that provides a Spanish version of the Body Image Scale. Our results show a stable factorial structure between samples with a single-factor solution and good psychometric properties, suggesting that it is a suitable tool for measuring body image concerns among Spanish-speaking cancer patients. Its brevity and comprehensibility allow a quick assessment both in clinical and research settings.

ABSTRACT

El objetivo principal de este estudio es comprobar si los niños con cáncer (en tratamiento con quimioterapia) presentan peor autoconcepto físico, menos autoestima y más ansiedad y depresión que los niños sanos (sin historia de cáncer) de los mismos rangos de edad (9-16 años) y condición social. Adicionalmente, se analiza la capacidad predictiva del autoconcepto y la autoestima sobre el malestar emocional. Se administró la versión española del PSDQ, CDI y STAIC a 30 niños con cáncer y 90 escolares sin historia de cáncer. Los resultados señalaron que no existían diferencias estadísticamente significativas entre ambos grupos en ninguna de las variables de estudio, excepto en dos de las 11 dimensiones del PSDQ, salud y flexibilidad. La autoestima fue el mejor predictor de depresión, mientras la salud y el autoconcepto predecían ansiedad (AU)


The main purpose of this study is to test if children with cancer receiving chemotherapy show a poorer physical self-concept, less self-esteem and more anxiety and depression than healthy children (with no cancer history) within the same age range (9-16 years old) and social condition. Furthermore, the capacity of self-concept and self-esteem to predict emotional distress is analyzed. The Spanish versions of PSDQ, CDI and STAIC were administered to 30 children with cancer and 90 healthy children. Except for the health and flexibility dimensions in the PSDQ, no significant differences between groups were found. Self-esteem was the best predictor of depression, whereas health and self-concept predicted anxiety (AU)

ABSTRACT

Temperaments are often regarded as biologically based psychological tendencies with intrinsic paths of development. It is argued that this definition applies to the personality traits of the five-factor model. Evidence for the endogenous nature of traits is summarized from studies of behavior genetics, parent-child relations, personality structure, animal personality, and the longitudinal stability of individual differences. New evidence for intrinsic maturation is offered from analyses of NEO Five-Factor Inventory scores for men and women age 14 and over in German, British, Spanish, Czech, and Turkish samples (N = 5,085). These data support strong conceptual links to child temperament despite modest empirical associations. The intrinsic maturation of personality is complemented by the culturally conditioned development of characteristic adaptations that express personality; interventions in human development are best addressed to these.
